Acromegaly The most common cause is a benign tumor in your pituitary gland, which is located under your brain. This tumor is not cancer. Because of the tumor, your body makes too much growth hormone. Once in a while, tumors in the pancreas, liver, or parts of the brain can cause high levels of growth hormone. That leads to higher levels of another hormone, called insulin-like growth hormone, which causes the symptoms you see.

Thyromegaly Thyromegaly is better known in simple terms as goiter. This means that the thyroid gland had grown into a much bigger size than the normal thyroid gland. This gland is located just at the base of the neck or just below the Adam’s apple, so as it grows beyond its normal size, it is much more visible. The thyroid is a butterfly-shaped gland that produces important thyroid hormones, which are important in the body’s metabolism.

- Genetic mutation responsible for 'gigantism' disease -- or acromegaly -- identified. FULL STORY. An international research team, spearheaded by scientists from the London School of Medicine and Dentistry, has identified the genetic mutation responsible for a disease known as gigantism or acromegaly.

Acromegaly When the pituitary gland produces excess growth hormone, this results in excessive growth – called acromegaly. The excessive growth occurs first in the hands and feet, as soft tissue begins to swell. This rare disease affects mostly middle-aged adults. Untreated, the disease can lead to severe illness and death.

What Are Pituitary Tumors? Anterior pituitary. Most pituitary tumors begin in the larger, front part of the pituitary gland known as the anterior pituitary. This part of the gland makes several hormones that control other endocrine glands. 1  Growth hormone (GH, also known as somatotropin) promotes body growth during childhood.2  If too much is made in a child they will grow very tall. 3  Normally, adults make only small amounts of growth hormone.his part of the gland makes several hormones that control other endocrine glands. 1  Growth hormone (GH, also known as somatotropin) promotes body growth during childhood. 2  If too much is made in a child they will grow very tall.

Acromegaly The hormone most often affected is called growth hormone, or GH. It is produced by the pituitary gland, a tiny organ at the base of the brain. Growth hormone promotes growth of bone, cartilage, muscle, organs, and other tissues. When there is too much growth hormone in the body, these tissues grow larger than normal. This excessive growth can cause serious disease and even premature death.

Pituitary Tumors 1 Growth hormone (GH). 2  GH is made in the pituitary gland (see figure below). 3  In a person with acromegaly, too much GH is released into the body. 4  Overproduction of GH causes changes in physical appearance and body function.cromegaly is generally caused by a noncancerous growth called a tumor or an adenoma located on the pituitary gland. The pituitary gland is a pea-sized structure located in the front of the brain, behind the eyes (see figure below). It is also commonly referred to as the master gland of the body.

Symptoms of acromegaly include abnormal enlargement in bones of the hands, arms, feet, legs, and head.n rare cases, non-pituitary tumors in the pancreas, lungs or adrenal glands may cause acromegaly. These tumors may directly produce excess growth hormone or they may produce growth hormone-releasing hormone (GHRH), which stimulates the pituitary gland to release GH.

- Acromegaly is a hormonal disorder that results from too much growth hormone (GH) in the body. The pituitary, a small gland in the brain, makes GH. In acromegaly, the pituitary produces excessive amounts of GH. Usually the excess GH comes from benign, or noncancerous, tumors on the pituitary.

What Are the Causes of an Enlarged Adrenal Gland? Different types of benign, or noncancerous, adrenal tumors prove a frequent cause of enlargement of the gland. Adrenal adenomas remain the most common type of benign adrenal tumors, representing over 50 percent of adrenal masses. Uncommon benign adrenal tumors include adrenal cysts and lipomas, or fat-derived tumors.Some adrenal adenomas produce hormones, including cortisol and aldosterone. Excessive aldosterone production from an adrenal adenoma commonly causes high blood pressure, muscle weakness, increased urination and thirst.verview. The adrenal glands, also known as the suprarenal glands, are small hormone-producing organs located just above each kidney. The adrenal glands produce several hormones, including adrenalin, cortisol and aldosterone.

Human Growth Hormone â Benefits, Side Effects, Dosages, Cost Acromegaly is a side effect of high levels of growth hormone in the body and can occur when the pituitary gland, with no other influences, produces high amounts of growth hormone, which are often caused by benign tumors on the pituitary gland itself.

Gigantism and Acromegaly Overproduction of growth hormone causes excessive growth. In children, the condition is called gigantism. In adults, it is called acromegaly. Excessive growth hormone is almost always caused by a noncancerous (benign) pituitary tumor.Children develop great stature, and adults develop deformed bones but do not grow taller.n adults, it is called acromegaly. Excessive growth hormone is almost always caused by a noncancerous (benign) pituitary tumor. Children develop great stature, and adults develop deformed bones but do not grow taller.

Papillary tumors of the pineal region Pineal region tumors are normally composed of a variety of cells including astrocytes, ganglion cells, blood vessels, and pinealocytes, which are the cells of this organ. Pinealocytes are specialized neurons, which are rich in monoaminergic neurotransmitters, including, serotonin, norepinephrine, and melatonin.

- Gigantism is abnormally large growth due to an excess of growth hormone (GH) during childhood, before the bone growth plates have closed (epiphyseal fusion). It causes excessive growth in height, muscles, and organs, making the child extremely large for age.

Acromegaly Overproduction of growth hormone (GH) by the pituitary gland over a long period of time causes acromegaly. There are several reasons for overproduction of GH. The most common reason is the presence of a pituitary adenoma, which is a benign (non-cancerous) tumor of the pituitary gland. These tumors produce excess GH.

acromegaly A rare disease resulting from excessive growth hormone caused by a benign tumor. If such a tumor develops within the first 10 years of life, the result is gigantism (in which growth is accelerated) and not acromegaly. Symptoms include coarsening of the facial features, enlargement of the hands, feet, ears, and nose, jutting of the jaw, and a long face.

Pheochromocytomas: Adrenal Gland Tumors Headaches, Anxiety, Nervousness, and Hypertension. Pheochromocytomas are tumors of the adrenal gland that produce excess adrenaline. Pheochromocytomas arise from the central portion of the adrenal gland, which is called the adrenal medulla. The adrenal medulla is responsible for the normal production of adrenaline, which our body requires to help maintain blood pressure and to help cope with stressful situations.

Pituitary gland The anterior pituitary (or adenohypophysis) is a lobe of the gland that regulates several physiological processes (including stress, growth, reproduction, and lactation). The intermediate lobe synthesizes and secretes melanocyte-stimulating hormone.his contrasts with the posterior pituitary, which originates from neuroectoderm. Endocrine cells of the anterior pituitary are controlled by regulatory hormones released by parvocellular neurosecretory cells in the hypothalamus.
